Julián Castro, rumored to be a potential vice presidential pick, said he is currently not being vetted by the Hillary Clinton campaign. However, his name is on a preliminary shortlist leaked this week. He also refused to speculate on who would make a good pick for VP.

“That is Secretary Clinton’s choice,” he said. “More important than that, she’s shown a history of good judgment.”

Julian Castro also emphasized that GOP state leaders are trying to distract voters “from the fact that they have bungled so much and now economically Texas is losing ground.”

His brother hammered at what he called “the arrogance and corruption” of state GOP leaders, including granting billions of dollars in no-bid contracts. GOP leaders have focused on suing the Obama administration, and pushing anti-immigrant and anti-LGBT policies.

“We can’t let them get away with that,” Castro said.

Secretary Castro also addressed concerns about how the Clinton campaign would bring Sanders supporters into the fold. He said he was confident that the Democratic Party would present a unified front in the November election.

“I believe that the vast majority of the folks who support Senator Sanders also will support Secretary Clinton because they understand the difference in values that she is espousing and the investments she would make.”
